To all whom it may concern:

Be it known that I, RHENART F. ERKnNs, a citizen of the United States, and a res1- dent of the city of New York, Astoria, Long Island Cit borough of Queens, 1n the county of ueens and State of New York, have invented a new and Improved Rad1ator for Water-Cooled Motors, of whlch the following is a full, clear, and, exact description.

This invention relates to radiators for water-cooled internal combustion engines or like motors and has particular reference to improved means for causing the rapld cooling of a relatively large volume of water.

Among the objects of the invention is to provide a radiator whose water chamber is so designed that the water is ma ntained in a large volume without subdlvlsions and thereby the danger of freezlng and bursting of an art of the radlator is reduced to a negligible quantity. Whereas 1n the ordinary radiator commonly used on automobiles the water passages are so slender that the water therein will freeze almost momentarily when the engine is idle, the danger of freezin and bursting of the rad ator is almost entirely eliminated by providing in this instance a tank wherein a body of water is maintained without narrow passageways.

Another ob'ect of the invention is to provide means or cooling a body. of heated water by a forced circulation of air drawn from outside of the front part of the machine, the air being caused to circulate upwardthrough the water and serving thereby to extract the heat.

Another object of the invention is to provide an air pump mounted on or operated from the motor shaft and serving to cause the forced circulation of air through the body of water, means being provided in connection with the air pump to control the admission; and exhaust of the air from the mechanism. I

With the foregoing and other; ob ects in view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction-disclosed or suggested herein,

- drawings like reference characters designate the same parts in the several views, and in which- Figure 1 is a vertical transverse section on the line 1'1 of Fig. 3.

Fig. 2 is a plan view, parts being broken away.

Fig. 3 1s a vertical longitudinal section substantially along. the longitudinal center draft regulator seen from the back of the" radiator looking forward.

Referrin now more specifically to the show my improvement carried by the front end of a motor vehicle includ- 1ng an en me casing 10, crank shaft 11, and waigr-coo ed radiator indicated as a whole at l The radiator includes a water tank 13 extending across the front thereof and adapted to be maintained supplied with water up to a level somewhat below the top, water being admitted to the radiator as usual by means of a filling tube 14 at the top of the hood 15. The water either from the filling tube 14 or from the hot water pipe 16 leading from the engine jacket is delivered into and through a water head 17 and thence through a neck 18 leading downward across the air manifold 19 extending across the full width of the hood 15 and from which there extend downward into the water tank 13 a plurality of air tubes 20, the lower otherwise open ends of which are normally closed by conical valves 21 seated normally upward by the pressure of water surrounding these valved ends of the tubes. These tubes 20 extend downward nearly to the bottom of the water tank.

A cool air duct 22 having open ends 23 extends downward along the sides of the water tank and across the bottom thereof in substantially U-form and below the ends of the tubes 20. These ends 23 are open to the atmosphere and insure that cool air may be admitted through either end thereof and drawn downward into the bottom portion of the duct whence it may be delivered able means may be rovided to operate the- (1 I show a sprocket 28 pump. To this en operating over large and small sprocket wheels 29 and 30 secured to the crank shaft -11 and counter shaft 31 respectively whereby the pump wheel will be driven at a higher rate of speed than the crank shaft and in the same direction.

The front and rear of the pump casing 26 are provided with circular openings 34 and the rear openings 34 are provided with a rotatable air admission control member 32 having a plurality of holes 33 adapted to register with other holes 34 formed in the rear wall of the fan chamber. The draft regulator 32 is mounted co-axiall of the counter shaft 31 and held in place y a rim 35. A handle 36 connected to the disk 32 serves to control its position. From the bottom of the water chamber 13 a pipe 37leads to the engine jacket, the water circulating in the direction of the arrows. At the top of the water chamber and communicatin with the air space 45 is an air port 38, the ow of air through it being controllable by means of a slide 39 or other uitable damper having a handle 40 for mani ulation, thence through space 45 into-o enings 34 to fan 27 where said warm air 1s mixed with cool air supplied and controlled by the slide or disk '32.

Also at the o posite end of the aforesaid port 38 in the ottom of the air manifold 19 1s provided an openin 41 as shown in Fig. 2 at the left side of t e center. Warm air 1 from the air manifold 19 may be discharged outward through: a discharge nozzle 42 which may lead to the atmosphere or may be utilized in cold weather for warming the body of the car by means of a tube, not shown, connected to the nipple 43 having a 1 valve 44 therein.

With the device designed and arranged as illustrated, and with the. air inlet controlling means 32 closed or substantially closed the power of the pump 27 may be exerted to force air or water vapors out through the discharge nozzle 42 and cause a corresponding intake of air through the air duct 22, the graduated portions of which will be admitted upward through the water at thenozzles 24 and thereby extracting su erfluous heat from the water'as the alr'bu bles up through it. Moreover a portion of the air acted upon by the air pump will be driven downward through the air tubes 20 causing t e opening of the valves 21 when the downward pressure of the air becomes superior to the upward ressure of the water below 9 "the valves and t is air'likewise will float upward through the water causing the agitation and rapid-"cooling thereof. Obviously the relative effects of the air pump and the circulation of air in and through the a paratus may be suitably re lated by ad ustin the valves 32, 39 an 44. claim: 1. In a radiator for water cooled motors, the combination of a tank for a body of water, means located at the rear of the tank to cause a forced circulation of air through the body of water, a U-shaped air admission tube leading from the atmosphere inward through the upper corners of the water tank and thence downward to the bottom of the body of water, said tube having at its lower portion a series of ports through which the air is caused to enter the water as a result of the action of theair forcing means, means providing for the circulation of water from the tank through the engine, and means to .cause the delivery of the hot water from the engineto be effective near the bottom of the supply of water.

2. In a radiator for water cooled motors, the combination of an upright tank for a 4 body of water, an air blower journaled at the rear of the tank, means to cause air currents to ass inward through the body of water and out through the top of the tank and thence through a space between the tank and theblower, said air current means including a bent pipe leading from the upper side portionof the tank and thence downward to the-bottom of the tank where a portion of the tube lies along the bottom of the tank, said bottom portion of the tube having a series of upwardly directed air I ports, valves normallykeeping these ports closed, but subject to'being opened by the force of the blower, and a series of vertical tubes serving to deliver the heated water, from the engine down into the body of water in the tank adjacent to the ported portion of the air tube.

3. In a radiator for water cooled motors, the combination of an upright rectangular tank for a supply of water, a blower casing s aced rearward from the water tank, a

b ower in the blower casing, means to actuate the blower coincidentally with the operation of the motor, the upper portion of the water tank providing for a pocket of air,

air passage means leading from said air pocket to the space between the tank and the blower casing, movable means to control the capacity of the air passage, means to vary the area of the air discharge opening from the blower casing, and a U-shaped fresh air pipe located in the water tank and'having 130 its upper ends open to the atmosphere at opposite sides thereof, the bottom of the tube lying along the bottom of the water in the tank and having a series of ports opening upward whereby fres air is admitted into direct contact with the water in the tank near the bottom thereof and caused to circulate upward through the water and thence outward through the blower.

4. In a radiator for water-cooled motors,

the combination of a tank supplied with water, a plurality of tubes leading downward into the Water, means to force air downward through said tubes, and valve means carried in the lower portions of the tubes to prevent the entrance of water into the tubes, but the discharge of the air downward therethrough when the air pressure becomes-superior to the upward water vpressure.
